Let's divide 37486721 by 215
We want to divide 37486721 by 215.

On to step 1:
The number 215 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 215

Going ahead to step 2:
If we divide 37 by 215, we get 0 and a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Bring next digit (4) of the dividend behind the 37 and repeat the process: 374 / 215

Let's proceed to step 3:
When dividing 374 by 215, we get 1 with a remainder of 159.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 215 from 374 to get 159.
Include the next digit (8) from the dividend after 159, then repeat: 1598 / 215

Let's proceed to step 4:
If we divide 1598 by 215, we get 7 and a remainder of 93.
Write down 7 as next digit of the result. 
Result so far: 17.0
Deduct 1505 from 1598 and we're left with 93.
Append the next digit (6) from the dividend to 93 and continue with: 936 / 215

Going ahead to step 5:
The number 215 fits into 936 4 times, leaving a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 174.0
The remainder is 76 after subtracting 860 from 936.
Append the next digit (7) from the dividend to 76 and continue with: 767 / 215

Advancing to step 6:
215 goes into 767 3 times with a remainder of 122.
Record the quotient 3 as the next digit in the result. 
Result so far: 1743.0
If we take 645 away from 767, we end up with 122.
Append the next digit (2) from the dividend to 122 and continue with: 1222 / 215

Step 7:
215 can be fit into 1222 5 times, resulting in a remainder of 147.
The number 5 becomes the next digit in our result. 
Result so far: 17435.0
The remainder is 147 after subtracting 1075 from 1222.
Append the next digit (1) from the dividend to 147 and continue with: 1471 / 215

Going ahead to step 8:
215 can be fit into 1471 6 times, resulting in a remainder of 181.
Write down 6 as next digit of the result. 
Result so far: 174356.0
If we subtract 1290 from 1471, we get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Let's proceed to step 9:
1810 divided by 215 is 8 with a remainder of 90.
Write down 8 as next digit of the result. 
Result so far: 174356.8
Subtracting 1720 from 1810 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 10:
The number 215 fits into 900 4 times, leaving a remainder of 40.
The next digit of our result is 4. 
Result so far: 174356.84
Subtracting 860 from 900 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
215 can be fit into 400 1 times, resulting in a remainder of 185.
Record the quotient 1 as the next digit in the result. 
Result so far: 174356.841
Subtract 215 from 400 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

On to step 12:
215 goes into 1850 8 times with a remainder of 130.
Use 8 as the next digit of our solution. 
Result so far: 174356.8418
Subtract 1720 from 1850 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 13:
When dividing 1300 by 215, we get 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 174356.84186
The remainder is 10 after subtracting 1290 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 14:
215 goes into 100 0 times with a remainder of 100.
The next digit of our result is 0. 
Result so far: 174356.84186
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 15:
215 can be fit into 1000 4 times, resulting in a remainder of 140.
The number 4 becomes the next digit in our result. 
Result so far: 174356.8418604
Subtract 860 from 1000 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 16:
1400 divided by 215 is 6 with a remainder of 110.
Use 6 as the next digit of our solution. 
Result so far: 174356.84186046
Subtracting 1290 from 1400 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

The final outcome is 174356.84186046, with a leftover of 1.1e-07.
